IMPROVEMENT IN HARVESTERS.` l

Specification forming part of Letters Patent N o. 172,050, dated J annary 11, 1876; application led March 1, 1875.

To all whom t may concern Beit known that l, MILTON L. PARRETT, of Marshalltown, in the county of Marshall and State of Iowa, have invented certain Improvements for Harvesters, of which the following is a specification:

The object of my invention is to construct a harvestingmaehine in such a manner that the cut grain will be automatically raked into and held by a gavel-holder for the binder, and, when bound, automatically delivered'to a bundle-carrier. It consists in a rake, a gavelholder, and a fork, formed, combined, and arranged relative to each other and the binders and drivers seats, and a bundle-carrier, all as hereinafterV fully set forth.

Figure l of my drawingis a perspective view, illustrating the manner of forming and mounting the rake. a is the rake, rigidly attached to the hub b. c is a fixed shaft, upon which the hub b turns and slides. d is a pitman,connected with the hub b by means ofthe swiveled joint e. f is an anti-friction roller, journaled to the hub b on the opposite side of the rake a, and in line therewith. A A represent a section of a rake-guide, in the form ot a grooved box running parallel with the 'shaft c. It is rigidly attached to the rear side of the harvester-body in any suitable manner. No. l is the elevated and rear portion ot a continuous groove, in which the roller f moves when the rake a is sweeping the grain-platform and gathering a gavel. No. 2 is the lower and front portion of the same continuous groove, in which the roller j' moves when the rake assumes a vertical position, as indicated by broken lines, and as required when it returns to make a successive sweep of the platform and to gather a second gavel.

Fig. 2 is a perspective view, illustrating the construction and operation of my gavel-holder. l 2 3 4 are bent arms, rigidly attached to the rock-shaft g, designed to be mounted upon the platform of the harvester. 5 6 7 S are hook-form arms, rigid on the bar h at their lower ends, and pivoted to the arms l 2 3 4 at the points where they cross each other. k k

is a jointed pitman, hinged to the bar h and a rock-shaft, m, designed to be mounted on the harvester and Acombined with the driving mechanism. n is a cam on the rock-shaft fm,

projecting through a slot in the end and bearing ot' the pitman lc. 4

Fig. 3 is a pivoted fork, designed to enter the gavel-holder and to be bound in the she-af, and then swing around and carry and deposit the bound sheaf in a bundle-carrier. o is the tine ot' the fork; p, its crooked shank; r, its bearing, designed to be rigidly attached to the harvester-platform. .s is a swivel journaled to the shank p, and hinged to a bent pitman, t. u is a swivel, pivoted to the crank t on the rock-shaft m, and hinged to the-pitman t. m is the rock-shaft, designed to be mounted on the harvester and actuated by the grooved cam-wheel B. G is the rigid axle of the camwheel B. It has a bevel-gear wheel on its end, designed to engage a corresponding bevel-gear wheel rigidly xed on the axle of the drivingwheel.

Fig. 4 is a perspective view of my complete harvester, showing the relative positions of the various parts and their co-operatiou. D D represent the frame and body ot' the harvester. E is the driving-wheel, mounted on suitable bearings attached to the frame.' G Gris a dumping bundle-carrier,| secured to the rear and central portion ot' the body D D. H is the drivers seat, mounted over the bundle-carrier G in any suitable way, and in such position relative to the bundleearrier that the driver can readily dump the bundles, Whenever desired, by pulling a lever. K is the binders seat mounted in an suitable wa inside of the driving-Wheel E, and faces inward, and is in such position relative to the gavel-holder that the occupant can readily reach around and bind the gavel in the holder.

In the practical operation ot' my harvester, the driving-wheel E, connected by bevel-gear wheels with the shat't C, actuates the grooved cam-wheel B to rock the shaft m, and thereby lalternately lengthens and shortens the jointed pitman d d, to move the rake a .and cause it to sweep the grainplatform, and gather and deliver a gavel to the arms l 2 3 4 of the gavelholder. The same motion ofthe rock-shaft fm and its cam n in the slotted bearing of the pitman 7c 7c will alternately lengthen and shorten the pitman, and cause it to rock the shaft g and close the upper and lower series of arms, to press the gavel, and at the same time elevateit'into a convenient position for the binder to pass a band around tne gavel and bind it. A band of straw, cord, or any other suitable material may be used. The same rocking motion of the shaft m also operates the fork op, and, by means of the swiveled pitinan t, causes the tine o to enter the gavel-holder simultaneously with the gavel, and to remain there until the gavel-holder opens, when it swings around toward the rear and carries the bound sheaf to the bundle-carrier G G, where the sheavesv may accumulate, to be dropped at the will of the driver.

I am aware that rakes, gavel-holders, and bundle-carriers similar to mine have been used, and that cut grain has been taken from the sickle and deposited from the machine in bound sheaves, but not without being lifted and handled by the manual labor of the binder; and Iclaim that my combination of elements, by means of' which the cut grain is automatically taken from the sickle and delivered in bound sheaves to the bundle-carrier Without being lifted by the binder, is distinctively new and greatly advantageous.

1. The gavebholder composed of the rock# shaft g, bar h, and the double series of bent arms 1 2 3 4 5 6 7 8, in combination with the jointed pitman It k and rock-shaft m, having cam n, substantially as and for the purposes shown and described.

2. rEhe pivoted fork op, having swivel s, in combination with the bent pitman t, swivel u, crank fu, and rock-shaft m, and gavel-holderg h, substantially as and for the purposes shown and set forth.

3. In a harvesting-machine, the rake a, the gavel holder and carrier g h, the pivoted fork o 10, and the bundle-carrier Gr, when arranged and combined relatively to each other and the binders seat K, substantially as described, to take the cut grain from the sickle and deposit it in bound sheaves.
